摘要
生态系统服务功能的价值量驱动力分析对于揭示生态系统服务功能变化规律和成因具有重要意义。本文基于2019年度湖南省公益林六大生态系统服务功能价值量评估结果,分析了湖南省不同自然地理区域公益林单位面积生态系统服务功能价值量与自然气候要素的相关性,并以此为基础,选取自然环境因素、社会经济因素和政策因素,共计14项具有典型代表性的公益林生态系统服务功能价值量驱动力指标,深入分析不同因素的影响程度。结果表明:政策因素、自然环境因素是湖南省公益林生态系统服务功能价值量的主要驱动力,社会经济因素是次要驱动力;最干燥季降水量、最热季降水量是自然环境因素中的主要驱动力因子,公益林面积、中央财政补偿资金是政策因素中的主要驱动力因子。
The driving force analysis of the ecosystem service value is of great significance to reveal the changes and causes of ecosystem service mechanism.Based on the evaluation of the service value of six ecological protection forest in Hunan Province in 2019,the relationship between the ecosystem services value of ecological public welfare forest and natural climate factors in different natural geographical regions of Hunan Province was analyzed.Then a total 14 factors(natural,socio-economic and policies factors)were selected for a further analysis.The results showed that policies and natural factors play the leading role,and then were socio-economic factors.Among the natural factors,precipitation of driest quarter and precipitation of hotest quarter are the two key factors.The area and central financial compensation fund are the main driving factors in the policy factors.
